All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The inventors have found, through research, that, in the prior art,
POTS: analog telephone service, a narrow band-like telecommunications tool, for carrying voice calls. As shown in fig. 1, POTS (PlainOldTelephoneService): the analog telephone service is connected to the voice gateway above via a twisted pair, which is called the point line, with 2 lines, a called a line (ground, output 0v voltage) and a called B line (output-48 v voltage).
In the prior art, the telephone line is moved into a user's home from a machine room, often has a long distance, is exposed to the sun in the outdoor air, and can cause the phenomenon that the telephone is not connected due to the problem of line quality if rubber is aged over time, for example, the line A is grounded (for example, the line A is exposed and connected with the ground through a telegraph pole), and the line A is connected with the ground due to the grounding of the line A.
When the user line exists in the condition, the user has a call incoming, the voice gateway equipment rings the user, the ringing is 75V alternating current (positive and negative electrode is periodically changed), under the condition that the line A is normal, no matter the line A is at 0V or 75V, the line A is not connected with the ground (no circuit path) and no current exists in the line A, and the user can normally ring. However, if the line a is grounded, and when the line a and the ground are connected (the line a and the ground are connected), a current exists in the line a when the line a outputs a voltage, the voice gateway device considers that the user is off-hook (the device detects that the user is off-hook and detects whether the current exists on the points line or not), the voice gateway device considers that the user off-hook signal is received, and then issues a stop ring to make a call (the user is not off-hook in fact), and in this case, the user is caused to malfunction and not be available.
In the prior art, when the problem occurs, the problem is solved by a physical means through manually replacing a telephone line from a machine room to a user's home, which is troublesome and labor-consuming, uneconomical and low in efficiency.
In order to solve the above problem, in an embodiment of the present invention, a method includes: when the voice gateway receives the incoming call of the outside line, the voice gateway controls to send a ringing signal to the user terminal; at the same time of ringing, the control starting circuit test function detects and judges whether the POTS circuit A line is abnormally locked; when abnormal locking of the A line is detected, entering a test resistance flow, detecting a resistance value between the A line and the ground wire, and judging whether the A line is grounded or not; when the line A is judged to be grounded, the ringing current of the call is controlled to be direct current ringing current. In the embodiment of the invention, when the telephone is unavailable due to the grounding of the POTS line A, the voice gateway detects that the A line is grounded, and when a user receives an incoming call and rings, the ringing current is controlled to be direct current ringing current, namely, voltage (for example, 75v ringing current of the output direct current) is not output on the A line during ringing, so that the problem that the A line is unavailable due to the grounding of the A line can be completely solved; providing convenience for users.
The voice gateway can configure the condition of detecting the grounding of the A line on the user line by default without carrying out automatic detection each time, thereby automatically solving the problem that the user is unavailable due to the grounding of the A line, saving manpower to locate the line user fault and increasing the good experience of the user.
Various non-limiting embodiments of the present invention are described in detail below with reference to the attached drawing figures.
As shown in fig. 2, the method for detecting and processing the grounding fault of the line a of the POTS line in the embodiment of the invention includes the following steps:
step S100, when the voice gateway receives an incoming call of the outside line, the voice gateway controls to send a ringing signal to the user terminal;
POTS (PlainOldTelephoneService): the analog telephone service, as shown in fig. 1, is connected to the voice gateway above by a twisted pair, which is called the point line, with 2 lines, a called a line (ground, output 0v voltage) and a called B line (output-48 v voltage).
POTS: in the analog telephone service system, a telephone is connected with a voice gateway through a telephone line, wherein the telephone line is moved into a user's home from a machine room, often has a long distance, is exposed outdoors in the air and is sunned in the sun, and the phenomenon that the telephone is not enabled due to line quality problems can occur if rubber is aged, for example, as shown in fig. 3, the rubber is aged, an A line is grounded (for example, the A line is exposed and is connected with the ground through a telegraph pole), and the A line is grounded and can be connected with the ground; there is a possibility that a problem of line quality may occur to cause a phenomenon that the telephone is not enabled.
In the embodiment of the invention, the grounding condition of the line A is taken as an example for illustration. When the voice gateway receives the incoming call of the outside line, the voice gateway controls the user terminal to send down ringing signals. Specifically, as shown in fig. 3 and 4, the telephone is connected to the voice gateway through telephone lines (line a and line B), and the application program APP of the voice gateway detects in real time whether an incoming call of the outside line is received; when the application program APP of the voice gateway receives the incoming call of the outside line, the control sends a ringing signal to the user side.
Step S200, at the same time of ringing, controlling a line test function to detect and judge whether a POTS line A line is abnormally locked or not;
the invention controls the starting line test function to detect and judge whether the POTS line A line is abnormally locked or not at the same time of ringing.
Specifically, when ringing, if the voice gateway receives an off-hook signal, the voice gateway sends out a stop ringing signal to the user terminal and controls to switch on the user telephone; when the call is put through and the other party is abnormally off-hook, the voice gateway receives the disconnection message and enters a voice release process, and the voice gateway detects that the telephone is not actually off-hook, howling is controlled to be sounded, and the voice gateway enters a lock line state; judging whether the POTS line A is abnormally locked or not through starting line test function detection; and when the A line abnormality is detected, judging that the A line of the POTS line is abnormally locked.
As shown in fig. 4, when the application APP of the voice gateway receives an incoming call from the outside, the application APP will send a ring to the telephone set at the user terminal through the analog chip, because the user a line is grounded, the voice gateway will immediately receive a false off-hook signal at the user terminal, send a ring to the user and turn on the telephone set of the user (the voice gateway thinks that the user is actually off-hook), because the user is not actually off-hook, the user at the user terminal of the calling party will hang up and disconnect, the voice gateway receives a disconnect message, enter a voice release process, will send busy tone to the voice gateway, because the voice gateway is not actually off-hook, the user will not hear any sound, after 60 seconds, the voice gateway will enter a ring-down state, and after 180 seconds, the voice gateway will enter a lock state, so as to protect the safety of the voice gateway.
Step S300, when abnormal locking of the A line is detected, a resistance testing process is carried out, a resistance value between the A line and the ground line is detected, and whether the A line is grounded or not is judged;
in the embodiment of the invention, when abnormal locking of the A line is detected, a resistance testing process is started, the resistance value between the A line and the ground line is detected, and whether the A line is grounded is judged.
Specifically, when the voice gateway is detected to enter a locking state, entering a test resistance flow, and detecting resistance voltage and current parameters among the A line grounding resistance, the B line grounding resistance and the AB line; when detecting that the grounding of the A line has resistance, the voice gateway judges that the grounding of the A line occurs.
For example, as shown in fig. 3 and fig. 4, when the voice gateway enters a lock-up state, the voice gateway APP starts a line test function (the function can test quality parameters of a line, such as a line grounding resistance, a resistance voltage and current between lines AB, and the like), the line a is not grounded under normal conditions, and the resistance between the line a and the ground is infinite. However, once the line a is grounded, the resistance value exists between the line a and ground. After detecting that the grounding resistance exists on the A line in the embodiment of the invention, the voice gateway considers that the grounding condition exists on the A line.
Step 400, when it is determined that the line a is grounded, the ringing current of the call is controlled to be dc ringing current.
In the embodiment of the invention, when the line A is judged to be grounded, the ringing current of the call is controlled to be direct current ringing current.
Specifically, when the line A is judged to be grounded, the voltage is not output on the line A when the ringing is controlled, and the ringing current of the call is controlled to be direct current ringing current. For example, when the line A is judged to be grounded, the ringing current of the call is controlled to be direct current ringing current, and the 75v ringing current of the output direct current is controlled; the output voltage of the A line is always 0V when the direct current ringing current is output.
That is, in the embodiment of the present invention, since the ground output of the line a is always 0 voltage, only an ac voltage is output during ringing, the present invention adopts that the voltage is not output on the line a during ringing (for example, 75v ringing current of dc is output), and the problem that the user is not available due to the ground of the line a is solved through a program, as shown in fig. 3 and fig. 4: in the embodiment of the invention, when the voice gateway detects that the user telephone line is grounded by the A line and the user telephone line receives an incoming call, the ringing current is controlled to be direct current ringing current (the analog user supports alternating current and direct current ringing current, the output voltage of the direct current ringing current A line is always 0V), the user can normally ring, the voice gateway can not receive current on the A line, and the problem that the user is unavailable due to the fact that the user is taken off the hook is solved by mistake.
In a preferred embodiment, the method for detecting and processing a line-a ground fault of a POTS line, after the step of controlling the ringing current of the call to be dc ringing current when it is determined that the line-a is grounded, further includes:
and the voice gateway changes the default configuration of the situation that the grounding of the A line is detected into the grounding of the A line corresponding to the grounding of the A line on the user line. In the embodiment of the invention, the voice gateway can configure the condition of detecting the grounding of the A line on the user line by default without carrying out automatic detection every time, thereby automatically solving the problem that the user is unavailable due to the grounding of the A line, saving manpower to locate the line user fault and improving the good experience of the user.
From the above, in the embodiment of the present invention, when the POTS line a is grounded to cause the unavailability of the phone, the voice gateway detects that the line a is grounded, and when the user receives an incoming call and issues a ring, the ring current is controlled to be a direct current ring current, that is, when the ring is issued, the voltage is not output on the line a (for example, the ring current of 75v for outputting direct current), so that the problem that the line a is grounded to cause the unavailability of the user can be completely solved; providing convenience for users.
The voice gateway can configure the condition of detecting the grounding of the A line on the user line by default without carrying out automatic detection each time, thereby automatically solving the problem that the user is unavailable due to the grounding of the A line, saving manpower to locate the line user fault and increasing the good experience of the user.
